What type of inheritance is ABO Blood groups?

Biology
1 answer:
AnnyKZ [126]3 years ago
7 0

Answer:

The inheritance of ABO blood groups corresponds to an autosomal codominant pattern.

Explanation:

The blood type is defined by the presence of surface antigens in the red blood cell, called A and B. The presence of each antigen is determined by a gene present on the parental chromosomes.

  • Blood type A corresponds to the presence of gene A, and its genotypic expression can be A/A or A/O.
  • Type B blood, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen.
  • AB blood -due to codominance- has one gene for A and another for B, with genotype A/B.
  • Blood type O, characterised by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.

The presence of an antigen A or B, suppresses the expression of blood type O, recessive, which will be possible only in its homozygous form.

The most plausible evidence that the development of cancer is a multistep process can be:
miskamm [114]

Answer:

D) observation that certain tumor-suppressor genes and oncogenes are involved in a sequential manner in the development of colon cancer

Explanation:

Cancer is defined as the abnormal growth of cells of the body. These cells multiply/replicate without control thereby forming a lump or tumor.

Cancer growth has 5 stages and they go though different multi level steps.Different finding backs this up and it includes observation about certain tumor-suppressor genes and oncogenes being involved in a sequential manner in the development of colon cancer.

Suggest a means by which you could separate mrna from the other types of rna in a eukaryotic cell
jok3333 [9.3K]

A method by which you could separate mRNA from the other types of RNA in a eukaryotic cell is oligo (dT) chromatography.

<h3>What do you mean by mRNA?</h3>

mRNA may be defined as a molecule in cells that holds codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm.

The mRNA can be easily isolated from other types of RNA by the most reliable and convincing method of oligo (dT) chromatography which is the magnetic separation method that bounds oligo (dT) molecules on the surface of paramagnetic beads.

Therefore, a method by which you could separate mRNA from the other types of RNA in a eukaryotic cell is oligo (dT) chromatography.

In Marker Analysis, how are STRs related to alleles? Be sure to define each term (STR and allele) and explain how the two result
Lisa [10]

Answer:

The number of STR repeats is unique and therefore it is considered as an allele of that <em>locus</em>

Explanation:

Short Tandem Repeats (STRs), also known as microsatellites or simple sequence repeats (SSRs), are short DNA sequences with a size of 1-6 nucleotide bases which may be many times repeated in tandem. STRs localize in specific regions of the genome (<em>loci</em>) and therefore they are molecular markers. Gel electrophoresis a technique used to separate DNA fragments based on their size. In consequence, the pattern of STR repeats or 'alleles' obtained by electrophoresis can be used to identify individuals. In a gel electrophoresis, STR markers produce different bands that run more slowly or faster on the gel in different lanes according to their size (e.g., more slowly >> higher size of the STR sequence), and thereby STR alleles are unique and serve to identify individuals.
